Issue with PlatformMobileHelper.as on Android 11

[Vincent Jugé]

Hello,

While debugging a flex mobile app on an android 11 phone, I get this 
trace statement at startup :

Error while reading build.prop file:Error #3001: File or directory 
access denied.

This error is triggered by the computeOSVersionForAndroid() method of 
the spark.utils.PlatformMobileHelper class when it tries to read the 
/system/build.prop file.
Accessing system files, even in read mode seems to be forbidden on 
Android 11.

This issue is not critical, but I don't see any possible fix without 
using a native extension (Thats what I do for now on a monkey patched 
version of the class)

Any idea ?

Vincent.
